Novel Bacillus thuringiensis toxins with hymenopteran activity are described.

Bacillus thuringiensis toxins active against hymenopteran pests

Novel Bacillus thuringiensis isolates with hymenopteran activity are described. Also described are toxins having the advantageous hymenopteran activity. This invention further concerns genes or gene fragments which have been cloned from the novel Bacillus thuringiensis isolates which have formicidal activity. These genes or gene fragments can be used to transform suitable hosts for controlling ants.

Bacillus thuringiensis gene encoding hymenopteran-active toxins

The subject invention concerns a novel microbe and genes encoding novel toxin proteins with activity against cockroaches. Cockroaches are common house pests, and they create problems in hospitals, the food industry and in agriculture. The novel Bacillus thuringiensis microbe of the invention is referred to as B.t. PS185L8. The subject invention also concerns the use of B.t. PS201T6 to control cockroaches. A truncated form of a toxin obtained from PS201T6 having particular activity to cockroaches is also claimed for use in controlling the pest. The spores or crystals of the two microbes, or mutants thereof, are useful to control cockroaches in various environments. The genes of the invention can be used to transform various hosts wherein the novel toxic proteins can be expressed.

Bacillus thuringiensis isolates active against cockroaches and genes

The subject invention concerns a novel microbe and genes encoding novel toxin proteins with activity against cockroaches. Cockroaches are common house pests, and they create problems in hospitals, the food industry and in agriculture. The novel Bacillus thuringiensis microbe of the invention is referred to as B.t. PS185L8. The subject invention also concerns the use of PS201T6 to control cockroaches. The spores or crystals of these microbes, or variants thereof, are useful to control cockroaches in various environments. The genes of the invention can be used to transform various hosts wherein the novel toxic proteins can be expressed.

The subject invention concerns novel microbes and genes encoding novel toxin proteins with activity against insect pests of the order Hymenoptera. Pests in the order Hymenoptera are common house pests, and they create problems in hospitals, the food industry and in agriculture. The novel Bacillus thuringiensis microbe of the invention is referred to as B.t. PS211B2. The spores or crystals of these microbes, or mutants thereof, are useful to control hymenopteran pests in various environments. The genes of the invention can be used to transform various hosts wherein the novel toxic proteins can be expressed.
